PRINTING-BAR.

SPECIFICATION formingpart of Letters Patent No. 645,658, dated March 20,1906.

Application filed February 21, 1898. Serial No. 671,169. (No model.)

To all whom it may concern:

Be it known that I, ERL V. BEALS, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Printing-Bars, ofwhich the following is a specification.

My invention relates to a printing bar or slug bearing on one edge thecharacters required to print anentire line. These bars have usually beencast in a single piece, necessitating the employment of a considerablequantity of metal, the frequent recasting of which occasions much waste.The casting of the entire slugin a single piece also requires aconsiderable portion of the whole time devoted to the operation ofcasting due to the cooling of the metal, which is prolonged both by thequantity of metal in the slug and on account of the heat of thecontiguous sur-' faces. A slug cast in a single piece furthermorerequires to be trimmed on its sides.

My invention has for its object to provide a printing bar or slug whichcan be produced more rapidly and economically and with greater facilitythan heretofore.

It consists in a blank or body portion of suitable material preparedforre'peated usefulness and provided with one or more aperturesextending therethrough from edge to edge and an edge portion moldedthereon bearing the printing characters to form a line, the molten metalbeing delivered by a suit able casting mechanism through said apertureor apertures in said blank into a space between the faces of aline ofassembled matrices and the edge of said blank which is presentedthereto. g

My invention furthermore consists in providing the blank or body portionof the printing-bar at any suitable point, but preferably at one end,with a small aperture communicating with the space into which the metalis cast, said aperture permitting the escape of air from said spaceduring the operation of casting and being designed to be closed as soonas the space and the air aperture itself is filled with metal; and myinvention furthermore consists in certain novel features and details ofconstruction, as hereinafter characters required to print an entireline.

Fig. at is a vertical section through an assembled line of matrices andthe upper portion of the melting-pot of a machine for producingprinting-bars, illustrating the method of delivering the soft or meltenmaterial through the holes or openings in the foundation-piece of myprinting-bar into the line-matrices to form the edge portion bearing theprintingfaces. Fig. 5 is a vertical section on the line 5 5 of Fig. 4:.

' fully described, and specifically pointed out l Referring to thedrawings, A represents my improved printing-bar, which is composed of ablank or foundation-piece b, composed of any suitable material-forexample, hard metal-upon one edge of which is cast or molded in anysuitable manner or in any machine adapted for the purpose an edgeportion 0, of soft metal or other suitable substance, designed tobearupon its face the printing letters or characters required for an entireline. One longitudinal edge of the portion 1) is pro.- vided withnotches d, into which fit correspondingly-shaped apertured projectionsor nipples e, Figs. 4 and 5, in the bottom of a narrow slot f, formed atthe top of a melting .pot or receptacle B,which may form a portion ofthe casting device of a machine for pro-.

ducing' printing-bars, 0 representing a line of assembled matrices usedin connection with said casting device. The blank or foundation-piece bis placed within the slot f, which forms the mouth of the melting-pot,leaving a molding-chamber g between the upper edge of the portion 1) andthe line of matrices G.

h, Fig. 5, represents a rotary valve'or cutoff placed Within a chamber7, immediately beneath the mouthpiece of the melting-pot, said valvebeing operated at the proper times to permit the soft or molten materialcontained in the pot to be forced through its mouthpiece and to cut itoff therefrom.

Extending through the blank or portion b in the direction of its widthfrom the bottom of the notches d to its opposite edge j is a series ofholes or openings k, registering with the corresponding orifices k inthe nipples a, through which the molten material contained in a pot B iscaused to pass or flow into the space or molding-chamber 9 between theedge j of the portion 1) and the matrices O, properly assembled to forma line of printed matter, the soft or molten material at the same timefilling a groove m, formed in the edge j of the portion b,which groove,together with the material in the openings 7c and at when hardened bycooling, forms a means for securely holding the edge portion 0 alinedand in place upon the portion 12.

Near one end of the edge j of the portion 12 is formed an additionalpassage or aperture n, communicating with the groove m and extendingdown into one of the notches d on one side of the adjacent opening Itand having no communication therewith nor with the orifices 7c of themelting-pot, but only with an exitaperture 19, formed in the valve h andits casing, said opening a forming an outlet for discharge of the airfrom the molding-chamber g during the inflow of the soft or moltenmaterial, which is designed to be injected into said molding-chamberfirst'through the aperture at the end of the blank opposite to the endwhich bears the air-aperture n and thence successively through the otherapertures in the order of their distance from said first aperture untilfinally the metal fills up said airaperture 11 also, at which time thefurther revolving of valve 7L closes the end of the air aperture.

At the opposite ends of the portion 17 are.

ing the printing characters to form an entire line. These notches q qalso serve as a means for further controlling the movements of theblanks and finished printing-bar during theformation of its edge in themachine and its delivery therefrom.

WVhile I have shown and make claim herein to a printing-bar having ablank portion to be repeatedly used and composed of harder mate- -rialor materials than the section which bears the line of printing-faces, itshould be understood that I claim as embodying a part of the inventionthe right to make these blankportions of the same material of which theprint-. ing-faces are composed, so that the printingbar so formed may beentirely recast after fulfilling the purpose for which it was formed.

While this method necessitates the continual remelting of a greaterquantity of metal than that herein more particularly specified and.

claimed, it still alfords the great advantage of permitting the castingand trimming of said blank portions to be done outside of and distinctfrom main composing and line-forming machines. I desire it also to beunderstood that I do not limit myself to the particular form of theprinting-bar herein specified, but claim such modifications as would besuggested to any skilled mechanic in the construction of the same.

I believe myself to be the first to provide a printing-bar in two parts,one of which becomes the mouthpiece of a casting device during theformation of such bar and having through its body a passage way or waysfor the molding material to enter the chamber in which is formed thesection of the bar bearing the printing-faces. I also further believemyself to be the first to provide a printingbar blank which has throughits body a passage-Way for the escape of air from the molding-chamberwhile that section of a printing bar bearing the printing-faoes is beingformed upon said blank.

What I claim as my invention, and desire to secure by Letters Patent,is-" 1. A blank for composite printing-bars having notches at itsopposite ends for the reception of means for controlling its movementsin a machine for producing printing-bars.

2. A blank or foundation-piece for printing bars or slugs consisting ofa body having a groove along one edge and apertures extendingtherethrough from said groove.

3. A blank or foundation-piece for printing bars or slugs consisting ofa body having notches at one edge in which terminate aper-' turesextending through said body.

4. A printing bar or slug consisting of a foundation or main portionhaving a single groove along one edge and apertures extendingtherethrough from said groove, and an edge portion bearing theprinting-faces to form a line, said edge portion extending into thegrooved edge and apertures in said main portion.

5. A composite printing bar or slug having its base or main portionprovided with apertures extending therethrough for the passage of softor molten material to form thereon a character-bearing edge, said mainportion being provided at one edge with notches in line with itsopenings for the reception of corresponding apertured projections at themouth of a receptacle containing soft or molten material which passesdirectly from said projections through the apertures in the main portionof the printing-bar to the moldingchamber.

6. The herein-described printing-bar, comprising a blank or foundationpiece having notches at its opposite ends and provided with a groovealongone edge, a series of notches in its opposite edge, apertures exthepassage of air While the edge piece is betending from the bottom of saidnotches to said ing molded thereon. 1o groove, and an edge portionbearing printing Witness my hand this 19th day of February, charactersto form an entire line molded upon A.
